I bought the David BB product in the PA sale, I had trouble getting to work, then I noticed the Read Me said you also need the David Head Morphs and David Body Morphs (didn’t say it prior to buying). I can’t find those in the store, I only have the David Base. Should I return the item or are those available anywhere?

I fear the morphs were vaulted a while back - and if they aren’t in the store that would explain the lack of a link to the required product. I would certainly open a support ticket, pointing out that the product page is wrong and asking what your options are - the morphs would not be free in any event, so if you have spent as much as you wish you should ask for a refund regardless.
